Earlier this year we conducted an environmental audit and decided to remove the “black carbon” colouring from our products because the “black carbon” colouring is both environmentally unfriendly to produce and adds nothing to the products that we sell. So over time we will run out of “black” product and be selling brown / natural colour sheets.However certain of our food processor clients require specific colours such as red, blue, green, etc. so that any pieces from the liner stand out during production, we will still offer these colours.
